Uninstall etcd operator

Note that the etcd clusters managed by etcd operator will NOT be deleted even if the operator is uninstalled.
This is an intentional design to prevent accidental operator failure from killing all the etcd clusters.
In order to delete all clusters, delete all cluster CR objects before uninstall the operator.

Delete deployment:

$ kubectl delete -f example/deployment.yaml

Delete leader election endpoint

$ kubectl delete endpoints etcd-operator

Installation via Helm

etcd-operator is available as a Helm
chart.
Follow the instructions on the chart to install etcd-operator on your cluster.
